The approach to scalability in Blockchain

source

Many blockchain today would love for nothing more but to have an increased transaction throughput, but for one reason or the other the have had to trade off scalability though that's understandable but there is a growing need for secured and decentralized blockchain to be scalable like the Bitcoin blockchain, one could only imagine how powerful the Bitcoin blockchain would really be if in addition to security and decentralization it's truly efficient and able to have increased transaction throughput.

When a blockchain is able to process considerably large data of transactions without any congestion whatsoever and without it leading to increased network fee then it could be said that such a chain is scalable. Really it's important for blockchain to achieve scalability since without it then mass adoption becomes even more difficult to achieve since the need for faster transaction processing method continues to grow as the world grows too.

Ofcourse the issue of the trilemma is one that blockchain has constantly being battling and is not being easy, most strong blockchain have often achieved that much security and decentralization only as a result of letting go of it's scalability and this has become an ever present and crucial issue in the crypto space making us wonder really is there is ever a good approach to achieve scalability in blockchain.

I believe so and hence I will be write on some ways I believe is the best approach towards blockchain scalability:

Good approach to blockchain scalability

One way this could be achieved is with sidechain, this could help ease off the pressure on the main chain as the sidechain connected to it would help to handle some very special task for the main chain which would thus help it not to be easily congested by weights of transaction it had to handle, so the sidechain which ofcourse is completely independent on it's own when connected to a main chain could be a very plausible approach to blockchain scalability especially that of the main chain.

Let's say Ethereum network for instance a main chain and it's sidechain being the plasma chain, delegating much of the transaction responsibility on plasma which is a side chain of Ethereum helps it reduce network congestion and gas fee which is as a result of piled up transactions, so that's exactly the purpose of sidechain whilst nothing should be taken from it because there are quiet capable of functioning independently but when connected to a main chain helps or is a sure way to achieve scalability in blockchain.

Another viable option also includes change in consensus mechanism, that could also help to achieve scalability, there are consensus algorithm which tend the be more scalable than others they could be used as improvement to the existing ones, delegated proof of stake (DPoS) and (PoS) could be used as an improvement to proof of work in a bid toward scalability in blockchain as these two are much scalable than proof of work so a switch to these scalable network could help achieve this.

Well leaning towards newer blockchains could also help as these are now designed to be scalable, yes new blockchain uses very unique consensus algorithm and this ensure that scalability is given top priority, so looking to these alternative blockchains could also be the answer I believe, and there are a lot of them really which could be used for this purpose.

For instance we have the solona blockchain designed with unique architecture having scalability in mind, and we might wonder really what's this unique architecture? well sol blockchain in an effort to ensure it's high efficiency and improved processing capabilities they combine proof of history (PoH) and proof of stake (PoS) to achieve this, the combination of this two consensus algorithm makes the solana much suited to be used as an alternative blockchain in an effort to achieve scalability in blockchain.

Apart from the solana blockchain there are also other blockchain with unique consensus mechanism which makes it much scalable and could be used as an alternative blockchain like Avalanche blockchain for instance which uses novel consensus protocol and this unique architectural design enables the Avalanche blockchain to be much scalable just like polkadot, polkadot uses parachains which operate on their own whilst achieving full communication with other parallel chain, the multi chain frame work of polkadot also allows it to scale considerably well which shows that it's also a much improved and alternative blockchain to scalability in blockchain.

Sharding is also another effective approach to scalability in blockchain, the arts of dividing the database of blockchain into small shards could help reduce the load on the blockchain as workloads are shared across the different smaller parts or shards and the workload reduction helps to ensure there is higher efficiency in blockchain and is able to scale a great deal and this sharding technique could be used for upgrade by blockchain lacking scalability. Others could also implement layer 2 solutions which has become a viable option for many blockchain to ensure it maintains scalability as many workload could be handled offchain only when necessary will it be handled on chain that will greatly reduce the load workload on the main chain helping to maintain scalability.

Conclusion

Indeed scalability could be achieved in blockchain through sharding or through layer 2 solutions or looking towards alternative chains designed majorly to prioritize scalability or switching towards a more favorable consensus mechanism or through implementation of side chain connected to the main chain, so all in all the approach to scalability in blockchain is very feasible due to all these.
